To all 'whom it moy-concern:

'Be 1t known that l, WILLIAM M. HANSEN,

a citizen of the United States, residing at struction, combination and arrangementof Oxford, in the county of Chester and State of Pennsylvania, have invented` new and useful improvements in Loading Apparatus, of which the following is a specification.

rlhis invention relates to a loading apparatus or attachment for wagons, such as farm wagons and the like, the object of the invention being to provide a simple and in expensive, and yet powerful, type of apparatus which may be readily applied to existing wagons and o erated in an easy and convenient-manner 'or elevating boxes'or bags of material, live stock, etc., into the wagon, and which when not in use may he moved to a nondnterfering position in which it will be automatically held or locked by its actu# ating gearing.

Afurther-object of the invention is to pro? vide an apparatus in which provision is made for accommodating objectsto le loaded which vary in height, and which is adapted to be firmly secured to the wagon box or bed.

With these and other objects in view, the invention consists of the features of conparts hereinafter fully described and claimed, reference being had to the accompanying drawings, in w lich:-

Figure 1 is a side elevation of the device applied to the rear end of a wagon-body with' the sling lowered for use. Fig. 2' is a similar view with the sling elevated. Fig. 3 .1s a top plan view of the device. Fig. 4 1s a View ofi one of the supporting irons or brackets. Fig. 5 is a cross-section on line 5-5 of Fig. 3. Fig. 6 is a detail View of one of the bearing sleeves.. Fig. 7 is a detail view of a portion of one of the frame arms.

ln carrying my invention into practice, l provide a pair of supporting brackets 1 for attachment to the rear end of the vehicle box or body 2. Each of these brackets consists of a horizontal. body portion 3 provided on its underside with tubular bearing bosses f1- and 5 and at its outer sido with a vertically extending flange 6 provided with attaching arms 7 )erforated at their upper or free ends, the body portion 3 being also provided betwcensaid bearings with an inwardly ex tending attachingv arm 8 perforated at its free end. The rear end of the body is d opreseed to form a supporting shelf 9 disposed in rear of the bearing 5, and this 'shelf is provided with an elongated portion 1G formed with a groove or recess 11 which is in communication at its-outer end with a vertical groove or recess 12 in the rear end of the flange 6.

The body portions of the brackets 1 extend beneath the bottom of the Wagon bed, while the flanges 6 bear against the outer faces ofv the sides of the bed, andthe brackets are attached to such portions of the box or bed by bolts 13 passing through the apertured ends of the arms 7 and 8, thus firmly attaching.

' the brackets in position near the rear end of the box or bed, as shown. When the breek# ets are thus applied the shelves 9 are arranged to receive the rear cross brace of the box and the grooves 11 and 12 the coacting securing bolts and fittings.. f

Journaled in the front and rear bearings 4 and 5 of the two brackets are bearing sleeves 14, cach of which is provided at its outer end with a head 15 to en age the outer face of the bracket and limit t 1e inward movement of L said sleeve.. The sleeves are provided with angular or non-circular hores for the passage of angular transverse shafts 16 and 17, the shaft 16 being journaled in the front bearings 4 and the shaft 17 in the rear bearings 5 of the two brackets, the an ular form of the bores of the sleeves 14 and t e corresponding forni of the 'shafts connecting said sleeves to turn with the shaft and to forrni the journals thereof.

Fitted upon the endsof the shaft 16 are eccentric gears 18 corresponding in form and arrangement, and each having an lan ular collar or opening for'the passage of the s aft,

--vided with a collar 2() secured to the shaft by this construction the a set screw 21. By shaft may be slid longitudinally into engagement with the gears and bearing sleeves from one side until the head 19 bears against the gear 18 at that side, after which by securing ds the adjacent the gear at the opposite side by the set screw 21v to the shaft, the parts will be secured tosie gether against relative movement. This f construction adapts the shaft and coperatingparts to be readily applied and removed.

-' e shaft 17 is similar in construction to ,5 'the shaft 16 and carries at its ends eccentric gears 22' which ,mesh with the gears 18, said shaft being extended through bearing sleeves 14 of the type described whichare journaled in the lrear bearings of the brackets. l'nasmuchas the gears 22 are mountedv and secured to the shaft 17 in the saine manner that the gears 18 are mounted and secured to the j shaft 16, the securing means ofthe two sets of by correspondgears and shafts are indicated ino* reference numerals.

llhe "gears are in the form of quadrants l whose curved 'surfaces are provided with teethwhich intermesh and thus connect the i two sets of ears .for simultaneous movement 20 to rotate t e shafts in unison. Each fri mary' or drive gear 1S is provided with -a guide 23 and a socket24 to receive the engaging-end of an operating lever 25, whereby motion may-be communlcated to rock the shaft 16 in reverse directions.` By this construction the lever ma be connected with the gear 18 at either lsi e of the vehicle body for use and removed after `use.

-Each gear 22 is provided with a guide loop or socket 26 for connection with and passage of the inner end of an arm or bar 27, which is secured thereto by a bolt or setescrew 28 and is formed at its mner end with an angular notch 29 to receiveand engage the shaft 17, by :which it is positively connected with the shaft and gear to swing in reverse directions therewith. The bar may also4 beformed with a notch 27 a' to receive and engage the lower Wall of the guide loop 26. The outer ends of the arms or bars 27 are each provided with a series of openings 30 for the reception of the g--ends of a cross rod or bar 31 which are threaded for the reception of securing. nuts 32'. The

, v'shaft 17, varms 27 and rod 3,1 form a swin ing frame operated by the gearing from the s aft V16,- and adapted in operation to swing'from fthefhorizontal position shown in'Fig. 1 in rear of the body 2, to the vertical position `shown 1n Fi 2, in vwhich the arms 27 pro- 'fject above t .esides of the body, while the rod 31 extendsl across the body at a point in advance of the rear endthereof."

@from therod- 31 is suspended a suitable for supporting the article which is to be 'loa ed yinto the wagonl rl`he sling shown in j the present instance comprises a pair of 'hanger chains 33 provided at their upper ends with hooks 34 to detachablygen a e the rod and connected at their lower en sl y diverginglbranch-chains 35 to the front and rear edges of the opposite-*ends of a board or lat- .orm' 36, on -w lch the article 'is rested. Vilhen the sling frame is arranged inthe osition' shown in Fig. 1 for operation,the s 'ng dependsxfrom the rod 31 to va point in close proximity to the ground to enable the article to be loaded to b`e`conveniently laced therevon, after which by swinging the ever 25 rearwardly the frame maybe elevated to the position shown in Fig. 2 to swing the sling into the rear end of the wagon body,4 so as to allow the article to be readily removed and placed at a suitable point within the body for transportation. A brace 31b is fixed to and depends Jronrthe center of the rod 31 to stay and support the upper end ot a like resting on the platform.

bag or the The forni of vsling shown 1s especially def signed i'or supporting and elevating boxes, bags of liour, potatoes, and other articles and substances, barrels and t-he like, and in order to provide for the convenient arrangement thereon of articles of considerable length or height, the'intermediate portion ofthe rod 31 is arched, as at 31", to permit the upper end of the bag or article to extend above the line of the ends of the rod, so that articlesl varying considerably in height may be readily applied and accommodated. The'hooks 34 bear against the shoulders formed by the ends of the arched portion, and thus are prevented from slipping inwardly relative to one another. ployed, however, for hoisting live stock and 1 other kinds of loads into the wagon which Other forms of slings may be emcannot be conveniently handled by the type of sling shown.

It Willwbe seen by reference to Fig. 1 that when thedevice is in position tor loading, M 1'0'0 the toothed portion/of the gears lfnearest their fulerum are in engagement with. the
